Short answer: the Final Audio E3000, though neither ranks well in its class. It ranks #1070 of 1291 in-ear headphones by sound quality, rated 2.6/5, at $46.60; the Anker Soundcore Space A40 ranks #1093, rated 2.5/5, and costs $54.99, so there is not much of a tradeoff to weigh. Both are rated below 3.0/5 among the 1291 in-ear headphones, so if sound quality matters, consider the Intuaura Reference 2019 instead, ranked #7 at $34.99.
Why pick the Final Audio E3000: Bass at 60 to 200 Hz sits about 5.5 dB above the Harman target in oratory1990’s measurement, and the low mids are lifted about 3.2 dB, giving a warm, full and weighty sound. Watch for: The strong bass and low mid lift can muddy vocals, and presence from 3 to 6 kHz is down about 3 dB with a 3.7 dB dip near 4.5 kHz, so voices lack clarity.
Why pick the Anker Soundcore Space A40: Active noise cancelling, LDAC streaming, IPX4 splash resistance and a claimed 10 hours per charge (50 with the case) make this a well equipped set of true wireless earbuds for the money. Watch for: Sub-bass falls 6 dB below target by 42 Hz and is 7.5 dB down at 30 Hz, so deep synth bass and movie rumble go missing.
Buy the Final Audio E3000. It is rated higher for sound quality than the Anker Soundcore Space A40 and costs less, so only choose the other one for a particular feature it does better.
